Protein synthesis The DNA in chromosomes contains genetic instructions that regulate development,  growth, and the metabolic activities of cells. The DNA instructions determine whether a  cell will be that of a pea plant, a human, or some other organism, as well as establish  specific characteristics of the cell in that organism. For example, the DNA in a cell may  establish that it is a human cell. If, during development, it becomes a cell in the iris of  any eye, the DNA will direct other information appropriate for its location in the  organism, such as the production of brown, blue, or other pigmentation. DNA controls  the cell in this manner because it contains codes for polypeptides. Many polypeptides  are enzymes that regulate chemical reactions and influence the resulting characteristics  of the cell. Thus, from the molecular viewpoint, traits are the end products of metabolic  processes regulated by enzymes. A  gene  is defined as the DNA segment that codes for
